FUEL INJECTOR INSPECTION

  1. INSPECT FUEL INJECTOR ASSEMBLY

    1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 11.6 to 12.4 Ω

      If the result is not as specified, replace the fuel injector assembly.

    2. Inspect the injector injection.

      CAUTION:

      Keep the injector away from sparks during the test.

      1. Connect SST (fuel tube connector) to SST (hose) with SST (hose band), and then connect them to the fuel pipe (vehicle side).

      3. Connect SST (adapter and hose) to the injector, and hold the injector and union with SST (clamp).

      4. Install a vinyl tube onto the injector.

        CAUTION:

        Install a suitable vinyl tube onto the injector to contain any gasoline spray.

      5. Tie the clamp and adapter together with a tie band as shown in the illustration.

      6. Put the injector into the graduated cylinder.

      7. Operate the fuel pump Click here.

      8. Connect SST (wire) to the injector and the auxiliary battery for 15 seconds, and measure the injection volume with the graduated cylinder. Test each injector 2 or 3 times.

        Note

        Always switch the voltage on and off at the auxiliary battery side, not the injector side.

        Standard Injection Volume
        Tester Connection Condition Specified Condition
        Positive terminal - Ground terminal Per 15 seconds 87 to 105 cc (5.3 to 6.4 cu.in.)
        Difference between each injector
        18 cc (1.1 cu.in.) or less

        If the result is not as specified, replace the fuel injector assembly.

    3. Check for fuel drop.

      1. In the condition above, disconnect the tester probes of SST (wire) from the auxiliary battery and check for fuel drop from the injector.

        Standard fuel drop
        1 drop or less per 20 minutes

        If fuel drop is not as specified, replace the fuel injector assembly.
